SIGNAL ATTACHMENT FOR WOOL OR WORS'IED CARDS.

Application filed February 5, 1925. Serial No. 7,057.

T 0 all whom it may concern:

Be it known that we, CLAIR S. TAsKnR, JAMES A. TABOR, and Jason F. SMALL, citizens of the United States of America, and residents of Corinna, in the county of Penobsco-t and State of Maine, have invented a new and Improved Signal Attachment for W001 or Worsted Cards, ofwhich the following is a description.

Our invention relates to asignal for W001 or worsted cards and particularly to an overhead signal, the overhead consisting of a rope of the wool or worsted passing about overhead guides from one machine unit (breaker) to another.

The general object of our invention is to provide a signal that will take the place of a man positioned at each breaker looking to the possible breaking of the rope constituting the overhead.

A more specific object of the invention is to provide a signal of an extremely simple character and of a nature that it may be relied upon to unfailingly function in case of the rope or overhead breaking.

The nature of our invention and its distinctive features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a plan View illustrating the application of our overhead signal to the successive breakers of a card, the figure including a diagrammatic view of the signal circuit;

Figure 2 is an enlarged elevation of the signal and overhead rope at the adjacent ends of two breakers;

Figure 3 is a transverse vertical section as indicated by the line 3-3 of Figure 2.

In the illustrated example the letter A designates the rope or overhead which is run through the carding machine from unit to unit, the units being designated by the letter B. The overhead run of the rope A between the respective units is guided about sheaves C and from each overhead run of the wool or worsted rope, the latter is guided through the machine in the usual manner. Only the overhead portions of the rope are shown in the illustration as our signal means is related to the overhead runs.

The letter D indicates the flaring tube through which the rope A passes at an end of each unit B and from the tube D, the rope A passes about a flanged pulley or drum 10- hereinafter called a drum. The shaft 11 of drum 10 is positioned in forks 12 at each side of the drum, said forks being on standards 13 rising from the frame of each unit B of the card.

A circuit closer is provided in accordance with our invention and in the illustrated e:-: ample, said circuit closer includes a. post 14 having a lateral contact arm 15 at right angles thereto extending adjacent to an end of shaft 11 and directly beneath the sameas will be readily understood from Figures 2 and 3. The rope A is so arranged that it maintains the drum 10 positioned in the forks 12 and above and out of contact with the contact arm 15. The post le -passesthrough an insulating bushing 16 in the frame of each unit B, there being a collar 17 on said post and resting on said bushing, the lower end of the post being threaded to receive a nut 18 whereby the post is firmly clamped to the bushing 16.

A condulet 19 is provided on each unit adjacent to and below the post 14 of said unit through which condulet conductors 20, 21 run. The one conductor 20 is held to the post 14 by the nut 18 so that said post constitutes one terminal of the conductor wires. The other conductor wire 21 is run to a terminal 22 on the frame of the unit B.

It will be seen that the drum 10 forms a guide means for the rope A and that said guide means is adapted to gravitate upon the breaking of the rope into engagement with the contact arm 15 for breaking the circuit.

With the above described arrangement and with the rope A unbroken and thus holding the drum 1O raised with its shaft 11 thus out of contact with the arm 15, the circuit will remain broken. Upon the breaking of the wool 0r worsted rope A the drum 10 will drop and its shaft 11 will contact with the arm 15, thereby closing the circuit at said arm 15 and the fork 12 which is in electrical connection with the terminal 22 so that the circuit will be completed through arm 15 and the shaft 11.

We have illustrated a circuit in which is a generator 23 and a transformer 24. Two of the units B are shown in Figure 1 equipped with our improved circuit closer. If the circuit be closed at the unit B marked at the left Number 1 the circuit will be from the post 14 of the circuit closer at said unit by wire a to switch Z) marked Number 1 and pertaining to the unit B, Number 1, from switch Z) by wire 0 to gong box cl marked Number 1 and pertaining to unit Number 1 by wire 1 by wire 6 to lamp marked Number 1 pertaining to unit N umber 1 by wire 9 to the secondary of the transformer 24 and from said transformer by wire it to return wire 7 leading to contact 22 of the unit Z) numbered 1. Similarly, if the circuit be closed by the described circuit closer at the unit 13, numbered 2, at the left, the current will pass from the post lt of said unitby Wire j to switch Z) numbered 2 by wire 70 to gong box d numbered 2 by wire Zto lamp f numbered 2, and thence by wire 9 to transformer 2d and by wires h and 2' to the terminal 22 of the unit B numbered 2. Thus, it will be seen that with the breaking of the rope at a given unit the gong at will be sounded and the lamp pertaining to the particular unit will be illuminated so that there is a visual and an audible signal given not only to indicate that the rope A has broken but locating the unit where the breakage has occurred.

We would state in conclusion that while the illustrated example constitutes a practical embodiment of our invention, we do not limit ourselves strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claim.

Having thus described our invention, we claim.

An electric circuit making attachment for sliver feed rolls in carding machines, comprising an t.shaped bar with a nut threaded upon one end thereof and a shoulder upon the bar adjacent said nut, whereby the last named end of said rod may be extended through an opening in a frame member of a carding machine and secured to said frame member in such a manner that the free end portion of the bar is disposed in the path of the upward and downward movement of a feed roll of said machine, means for insulating the secured end of the bar from the machine frame member, and means whereby upon the feed roll engaging said free end of the bar an electric circuit will be established.
